The chassis 10 is formed by sheet metal processing, and the front end of the bottom plate 13 is bent upward at a substantially right angle to form a front plate 14, and the upper end of the front plate 14 is bent rearward at a substantially right angle to form a folded piece 15. ing. Then, an opening 16 is provided by cutting out the lower end of the front plate 14 in the shape of a rectangular window, and adjacent to this opening 16, the front end of the bottom plate 13 is extended from the outer lower part to the inner upper part, leaving both ends in an arch shape. A protruding projection 17 is provided, and the folded piece 15 is provided with a screw hole 1.
8 is provided. The front panel 11 is formed by aluminum extrusion molding, synthetic resin integral molding, etc., and is provided with an upper end piece 19 and a lower end piece 20 that extend rearward from the upper and lower ends of the front plate 24 at approximately right angles so as to have a substantially U-shaped cross section. The lower end piece 20 has an engagement piece 21 that extends further rearward from here and is inserted into the opening 16.
An engagement hole 22 that fits into the protrusion 17 is provided at a position corresponding to the protrusion 17 of the engagement piece 21, and a screw hole 23 is provided in the upper end piece 19 in correspondence to the screw hole 18. There is.

If you tighten and fix it with screw 12 through 3 and 18,
The attachment of the front panel 11 to the chassis 10 is completed. When disassembling, work in the reverse order of assembly, remove screw 12, and connect protrusion 17 and engagement hole 22.
All you have to do is disengage it. In this way, when assembling or disassembling, by tightening or loosening the screws 12 only from above, there is no need to use screws from below, and the device can be assembled or disassembled without having to turn it over or pull it back.
Work is done easily and easily. Moreover, when the protrusion 17 and the engagement hole 22 are engaged, the screw holes 23 and 18 do not need to be aligned in the lateral direction, and only need to be slightly aligned in the depth direction, and work efficiency is greatly improved.
